Sputter Yields from Titanium and Tantalum in a 1.5 kV Mercury Ion Engine Beam.
Abstract
Variation of sputter yield from titanium and tantalum was measured with respect to incident angle of 1.5 kV mercury ions, with a view to determining their suitability as target material for an ion engine test facility. Neither has the resistance to sputter damage that had been hoped for, but, since other materials are even less resistant, it is suggested that they are preferable to other common engineering materials. For comparison, a few measurements were made for silicon carbide, zinc and brass. (Author)
